The Mars surface is ‘rippling’ – Is it the wind, or is it a sandworm happy to see me?

Winds…

Seriously, NASA?

The idea that strong winds are pushing the sands on Mars shows such limited vision…

[via UPI] LAUREL, Md., Nov. 18 (UPI) — NASA’s Mars Reconnaissance Orbiter has captured images of sand dunes and ripples moving across the surface of Mars at dozens of locations, U.S. astronomers say.

The shifting of the dunes and ripples up to several yards reveals the planet’s sandy surface is more dynamic than previously thought, they said.

“Mars either has more gusts of wind than we knew about before, or the winds are capable of transporting more sand,” Nathan Bridges, planetary scientist at the Johns Hopkins University Applied Physics Laboratory in Laurel, Md., said in a release Friday.

While red dust swirls around Mars in storms and dust devils, the planet’s dark sand grains are larger and harder to move, astronomers said.

Less than 10 years ago scientists thought the dunes and ripples on Mars either did not budge or moved too slowly for detection.

In the thin Martian atmosphere stronger gusts of wind are needed to push a grain of sand, and wind-tunnel experiments have shown a patch of sand would take winds of about 80 mph to move on Mars compared with only 10 mph on Earth. [Read More]

A better idea?

Oh, yeah…

SANDWORMS!

Now THAT idea is inspired, because in truth…

When it comes to alien worlds?

Aren’t they all made a tiny bit better by the idea of sandworms?

Why, yes…

I think they are.
